Android: how to add a contact to the SIM using the SDK?

Question

I am writing an application which writes contacts in the SIM card of an Android phone. I am stuck at the point where the phone number is added: an exception occurs with no apparent reason.

Here is a snippet of code.

import android.app.Activity;
import android.content.ContentResolver;
import android.content.ContentUris;
import android.content.ContentValues;
import android.provider.ContactsContract.RawContacts;
import android.provider.ContactsContract.Data;
import android.provider.ContactsContract.RawContactsEntity;
import android.provider.ContactsContract.CommonDataKinds.Phone;
import android.provider.ContactsContract.CommonDataKinds.StructuredName;
import android.provider.ContactsContract.RawContacts.Entity;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.widget.TextView;
[...]
try{
            // add a row to the RawContacts table
     ContentValues values = new ContentValues();
     values.put(RawContacts.ACCOUNT_TYPE, "com.anddroid.contacts.sim");
     values.put(RawContacts.ACCOUNT_NAME, "SIM");
     Uri rawContactUri = getContentResolver().insert(RawContacts.CONTENT_URI, values);

            // get the ID of the newly-added line
     long rawContactId = ContentUris.parseId(rawContactUri);

            // add a "name" line to the Data table, linking it to the new RawContact
            // with the CONTACT_ID column
     values.clear();
     values.put(Data.RAW_CONTACT_ID, rawContactId);
     values.put(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE);
     values.put(StructuredName.DISPLAY_NAME, "Name");
     cr.insert(Data.CONTENT_URI, values);
            // this insert succeeds

            // add a "phone" line to the Data table, linking it to the new RawContact
            // with the CONTACT_ID column
     values.clear();
     values.put(Data.CONTACT_ID, rawContactId);
     values.put(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE);
     values.put(Phone.NUMBER, "+12345678901");
     values.put(Phone.TYPE, Phone.TYPE_MOBILE);
     cr.insert(Data.CONTENT_URI, values);
            // this insert fails with a NullPointerException
}
catch(Exception e){
    String xx=e.toString();
    System.out.println(xx);
}

The application has permissions android.permission.READ_CONTACTS and android.permission.WRITE_CONTACTS.

The phone shows a contact with the name but no phone (incidentally, adding the phone to that contact using the normal UI results in a new contact being added, with name and phone, and the old contact with name only staying).

Any idea why the third insert (the second in the Data table) fails, while the 2 previous ones (1 in RawContacts and 1 in Data) succeed?

Answer 1

values.put(RawContacts.ACCOUNT_TYPE, "com.anddroid.contacts.sim");

anddroid? I didn't look at the rest, but might be worth deleting a 'd'
